RemoveFailedHost

To remove failed host (which is no longer exist, bacause is the totally crashed) try this on the pool master:

Determine if there is no VM running state on the filed host:

xe vm-list

If it is running reset the VM power state:

xe vm-reset-powerstate force=true vm=<uuid-of-the-running-vm-on-the-failed-host>

Destroy, forget failed host:

xe host-list
xe host-forget uuid=<uuid-of-the-failed-slave>

If there will still remain local storages of the removed host in the pool, forget them:

xe sr-forget uuid=<UUID>
